Sorry all the 14 pairs.
Yes, pairs as in the text and image.


I'm still trying to absorb your code.
Am a newbie at this.


Thanks

Let me try to break it down for you..

PHP Code:

// suck the remote file into a string
$remote_site = join('', file("http://remote.domain.com/index.php") );

// now, pattern match for the desired text, in this case,
// $matches[3] will contain the value of the first red block (the name-like thingy)
//$matches[5] will contain the value of the second red block (the image source)
preg_match_all(
    "|<tr>(.*)<a name=\"(.*)\">(.*):</a>(.*)<IMG SRC=\"(.*)\"(.*)</tr>|Ui",
    $remote_site, $matches);

/**
 * $matches now looks like this:
 * $matches[3][0] = first match for the name block
 * $matches[5][0] = first match for the image block
 * $matches[3][1] = second match for the name block
 * $matches[5][1] = second match for the image block
 * etc.
 */

// loop through all the matches
for ($i=0; $i<count($matches[3]); $i++) {
    // put the name/image info into more user friendly variables
    $name = $matches[3];
    $image = $matches[5];
    
    // find out what the image source was...
    if (strstr($image,'grnball.gif')) {
        // the image source contains "grnball.gif",
    }
    else {
        // the imag source does not contain "grnball.gif",
        // so it must be "redball.gif"
    }
    
    // do your thingy
    // you might print a new table using the $name/$image from the other site
} 


I hope that helps (probably not =P). If you have a specific question, those are easier to answer.

means I got to repeat that 14 times for the pairs?

and add $matches(0) for all the pairs?

[Mark Hensler]

No, it is already looping through all the pairs. See where I said "// do your thingy"?

Try it.. just make a new file, and through this in there....

PHP Code:

<?
$remote_site = join('', file("http://remote.domain.com/index.php") );

preg_match_all(
    "|<tr>(.*)<a name=\"(.*)\">(.*):</a>(.*)<IMG SRC=\"(.*)\"(.*)</tr>|Ui",
    $remote_site, $matches);

for ($i=0; $i<count($matches[3]); $i++) {
    $name = $matches[3];
    $image = $matches[5];

    echo "|" . $name . "|" . $image . "|";

    if (strstr($image,'grnball.gif')) {
        echo "the image is a green ball" . "|";
    }
    else {
        echo "the image is a red ball" . "|";
    }
    
    echo "<br>\n";
}
?>

Warning: file("http://ulitma.lightning.net/uo/index.html") - Undefined error: 0 in /usr/local/www/vhosts/nettiq.com/htdocs/serverstats.php on line 2

Warning: Bad arguments to join() in /usr/local/www/vhosts/nettiq.com/htdocs/serverstats.php on line 2

I got this error when I try to run the php script.

[Mark Hensler]

That URL doesn't work for me.

[Saint]

my mistake
typo
http://ultima.lightning.net/uo/index.html

I corrected it and when i run the php
it gives me a blank screen.

[Mark Hensler]

try this:

PHP Code:

<?
echo "Yes, I'm running<BR>\n";

$remote_site = join('', file("http://remote.domain.com/index.php") );

preg_match_all(
    "|<tr>(.*)<a name=\"(.*)\">(.*):</a>(.*)<IMG SRC=\"(.*)\"(.*)</tr>|Ui",
    $remote_site, $matches);

echo "begining loop<BR>\n";

for ($i=0; $i<count($matches[3]); $i++) {
    $name = $matches[3][$i];
    $image = $matches[5][$i];

    echo "|" . $name . "|" . $image . "|";

    if (strstr($image,'grnball.gif')) {
        echo "the image is a green ball" . "|";
    }
    else {
        echo "the image is a red ball" . "|";
    }
    
    echo "<br>\n";
}
?>

[Saint]

trying now.

[Saint]

Nope.

Only get this 2 line

Yes, I'm running
begining loop

I should replace just the

$remote_site = join('', file("http://remote.domain.com/index.php") );

to http://ultima.lightning.net/uo/index.html right?

all the code stays.
